Abstract

The invention belongs to the field of geothermal geochemical exploration, and particularly relates to a concentration and enrichment device and method for rare gas in soil gas and application of the concentration and enrichment device and method. The concentration and enrichment device comprises a main bottle body; the bottle opening is formed in the top of the main bottle body and is sealed by a rubber plug, and a glass long tube is inserted into the rubber plug; the three-way pipe fitting is arranged at the side part of the main body bottle body and is communicated with the main body bottle body; the outer tank is used for containing the main bottle body and the refrigerating fluid, so that the main bottle body is soaked in the refrigerating fluid; and the outer tank is connected with the three-way pipe fitting. Aiming at rare gas in soil gas, the concentration and enrichment device can be used for removing interference, ensuring that the loss of collected gas components is reduced, reducing errors, and effectively enriching and concentrating target components, so that the detection precision is improved, and accurate effective data of the gas components are obtained.

Description

technical field [0001] The invention belongs to the field of geothermal and geochemical exploration, and more specifically relates to a device for concentrating and enriching noble gases in soil gas, a method for concentrating and enriching and its application. Background technique [0002] Oil and gas geochemical exploration is referred to as oil and gas geochemical exploration. It is an important means and working method in oil and gas exploration, and it is also an important branch of applied geochemistry. It requires data obtained by modern geochemical analysis methods to help find oil and gas reservoirs. Its theoretical basis is that the migration of hydrocarbons produces a variety of geochemical phenomena in the surrounding rocks and surface soil and the fluids contained in them, forming a variety of geochemical halos, resulting in hydrocarbons and various compounds and their elements and isotopes. Changes in points and content (abnormal). [0003] Oil and gas geoch...
